Answer:

8.0

Step-by-step explanation:

The attached shows guesses until we have an answer accurate to 6 decimal places. Rounded to 1 decimal place, the answer is 8.0 years.

This (8 years) was our initial guess, based on the "rule of 72" which says the doubling time for 9% interest is 72/9 = 8 years.

Our second guess, at 8.1, was farther away from the doubled value, so the first guess at 8.0 is closer.

t = 8.0
